Example 1 with IdController

use of org.neo4j.kernel.impl.storageengine.impl.recordstorage.id.IdController in project neo4j by neo4j.

the class IdReuseTest method sequentialOperationRelationshipIdReuse.

@Test
public void sequentialOperationRelationshipIdReuse() {
    Label marker = Label.label("marker");
    long relationship1 = createRelationship(marker);
    long relationship2 = createRelationship(marker);
    long relationship3 = createRelationship(marker);
    assertEquals("Ids should be sequential", relationship1 + 1, relationship2);
    assertEquals("Ids should be sequential", relationship2 + 1, relationship3);
    final IdController idMaintenanceController = getIdMaintenanceController();
    deleteRelationshipByLabelAndRelationshipType(marker);
    idMaintenanceController.maintenance();
    assertEquals("Relationships have reused id", relationship1, createRelationship(marker));
    assertEquals("Relationships have reused id", relationship2, createRelationship(marker));
    assertEquals("Relationships have reused id", relationship3, createRelationship(marker));
}

Example 2 with IdController

use of org.neo4j.kernel.impl.storageengine.impl.recordstorage.id.IdController in project neo4j by neo4j.
